Bug 320835

Application: plasma-desktop (4.10.3)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-23-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Logging out, shutting down, or restarting.

- Unusual behavior I noticed:
Plasma crashes right before the desktop shuts down.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
